用稀释法求得了由自制的7种烷基芳基磺酸盐复配体系(AAS)/正丁醇/正癸烷/水组成的W/O型微乳液的结构参数,还求得了醇从油相转移到界面时的标准自由能,并计算出标准焓变和标准熵变.探讨了烷基芳基磺酸盐平均分子量及其分布对结构参数及热力学函数的影响.结果表明,分散相有效半径Re,内核水半径Rw,二者之差di和表面活性剂分子在每个液滴中的平均聚集数元值均呈现为正态分布＜递减分布＜均匀分布＜递增分布＜反正态分布；分散相颗粒总数Nd和分散相界面外层总面积Ad值均呈现为正态分布＞递减分布＞均匀分布＞递增分布＞反正态分布；-△G0o→i值呈现为正态分布(5.36 KJ/mol)＜递减分布(5.49 kJ/mol)＜均匀分布(5.64 kJ/mol)＜递增分布(5.78 kJ/mol)＜反正态分布(6.01 kJ/mol)；△S0o→i值呈现为正态分布(26.88 J/( mol·K))＜递减分布(27.12 J/( mol·K))＜均匀分布(27.60 J/( mol·K))＜递增分布(28.06 J/( mol·K))＜反正态分布(29.23 J/( mol·K))；Rw、Re、(-n)、di、-△G0o→i、△H0o→i和△S0o→i值均随磺酸盐平均分子量的增大而增大；Nd、Ad值均随磺酸盐平均分子量的增大而减小；且在实验范围内,结构参数、-△G0o→i、△S0o→i与磺酸盐平均分子量均呈线性关系；后两者分别为y=0.0586x - 17.916,y =0.2203x -61.275.
